Description

The invention relates to a method for packaging material to be packaged in an outer packaging of cardboard with a bottom, with parallel and spaced from the bottom lid and with the bottom and the lid interconnecting side walls. In addition, the invention relates to an outer packaging of cardboard for receiving packaged goods with a bottom, a parallel and spaced from the bottom lid, the bottom and the lid interconnecting side walls and a cavity in the interior of the outer packaging above the packaged goods, the interior of the Depending on the degree of filling, the outer packaging more or less fills.

In mail order in particular, there is a need to ship the packaged goods largely with standardized outer packagings made of cardboard. The standardized outer packaging has, for example, dimensions (L x W x H) of 30 x 16 x 13 cm to 70 x 60 x 45 cm.

When using standardized outer packaging regularly remains above the packaged a cavity inside the outer packaging. In order to protect the packaged goods during transport from damage, at least this cavity is usually filled with a packaging pad. As a packaging pad, for example, paper, wood wool or bubble wrap for cavity filling into consideration.

Filling the cavities with packaging pad is time consuming and expensive.

From the DE 601 21 401 T2 A method is known for packaging packaged goods in an outer packaging made of cardboard with a bottom, with lids arranged parallel and spaced from the bottom, and with side walls connecting the bottom and the lid, comprising the steps

• 3füllen the outer packaging with packaged goods with the lid open,
• Inserting a flat inlay into the outer packaging,
• Aligning flaps of the inlay parallel to the side walls of the outer packaging,
• Joining the inlay to the side walls by gluing the flaps to the insides of the side walls. For bonding serve holding devices and actuators, which are moved with the tool for inserting the flat inlay. The fixtures and actuators can also be replaced by staplers, provided the flaps are stapled to the insides of the side walls and not to be glued.

The DE 20 2012 004 391 relates to a device for securing articles in an open-topped container by means of an inlay. Before inserting the inlay in the 3ehälter the objects in it are measured in height. Then the inlay is pushed into the container until just above the measured height. The side flaps of the inlay are thereby fixed by lateral suction cups and held at an angle of less than 90 degrees to the inner blanking surface, so that the stitching tabs form an acute angle with the side walls of the outer packaging. The suction cups are then extended to print the side flaps against the inside of the container wall. The glue is pressed and the inlay is connected to the container wall.

Based on this prior art, the invention is therefore based on the object to provide a method of the type mentioned for packaging of packaged goods, in which a sufficient protection of the packaged goods with only partial use of the interior of the outer packaging without packaging pad or is achieved with a smaller amount of packaging cushion.

• Befüllen der Umverpackung mit Packgut bei geöffnetem Deckel,
• Einsetzen eines flächigen Inlays mit mindestens zwei jeweils an gegenüberliegenden Längsseiten des Inlays angeordneten Heftlaschen in die Umverpackung,
• Ausrichten von Heftlaschen des Inlays parallel zu den Seitenwänden der Umverpackung,
• automatisiertes Erfassen der Position des Inlays in der Umverpackung, wobei das automatisierte Erfassen der Position des Inlays mittels eines in Richtung (Y) des Inlays verfahrbaren Schaltelementes erfolgt, das bei Berührung des Inlays oder Annäherung an das Inlay betätigt wird,
• Positionieren mindestens eines Heftwerkszeuges abhängig von der erfassten Position des Inlays an der Außenseite der Seitenwände der Umverpackung auf Höhe der Heftlaschen, wobei das Positionieren des mindestens einen Heftwerkzeugs mit einer Positioniereinrichtung erfolgt, die abhängig von der erfassten Position des Inlays gesteuert wird,
• mindestens ein Heftamboss abhängig von der erfassten Position des Inlays an der Innenseite einer der Seitenwände der Umverpackung auf Höhe der Heftlaschen positioniert wird und
• Aktivieren des Heftwerkzeugs zum Befestigen der Heftlaschen an den Seitenwänden, wobei jedes Heftwerkzeug nach der Positionierung des Heftambosses eine durchgehende Heftung urchführt.

This object is achieved in a method for packaging packaged goods cer mentioned above with the following steps:

• Filling the outer packaging with packaged goods with the lid open,
• Inserting a flat inlay with at least two stapling straps arranged in each case on opposite longitudinal sides of the inlay into the outer packaging,
• Aligning tabs of the inlay parallel to the sidewalls of the overpack,
• automated detection of the position of the inlay in the outer packaging, wherein the automated detection of the position of the inlay is effected by means of a switching element movable in the direction (Y) of the inlay, which is actuated upon contact of the inlay or approach to the inlay,
• Positioning at least one stapling tool depending on the detected position of the inlay on the outside of the side walls of the outer wrapping at the level of the stapling tabs, the positioning of the at least one stapling tool being carried out with a positioning device which is controlled as a function of the detected position of the inlay,
• at least one stitching anvil is positioned at the level of the fastening tabs depending on the detected position of the inlay on the inside of one of the side walls of the outer packaging, and
• Activating the stapling tool to secure the stapling tabs to the sidewalls, each stapling tool performing a stapling operation after positioning the stapling anvil.

The flat inlay fixes the packaged goods between the floor and inlay. This prevents that the packaged goods can move uncontrollably in a cavity in the interior of the outer packaging above the packaged goods. The enclosed between the inlay and the bottom of the outer packaging can be filled in addition to protecting the packaged goods with small amounts of packaging pad. The inlay is preferably arranged parallel to the bottom surface of the cubic outer packaging. However, it can also be arranged obliquely relative to the floor surface. Also in this case, the inlay preferably fills the entire cross section of the outer packaging, in order to ensure a complete separation between packaged goods and the cavity above.

In order to be able to carry out the method according to the invention with the high speed required for mail-order sales, a high degree of automation is sought for its implementation. The insertion of the flat inlay, the detection of the position of the inlay and the fixing of the inlay on the side walls are fully automatic.

The detection of the position of the inlay is carried out in particular with a button. Alternatively, a probe detects the position of the inlay.

Depending on the detected position, at least one stapling tool is controlled by means of a positioning device. In addition to the position of the inlay, the measuring device can detect the size of the outer packaging in order, in particular automatically to bring about the size of the outer packaging of each stapling tool to the outside of the carton and / or to determine the number of stapling.

The positioning device may be a conventional slide-guided multi-axis system. The positioning takes place on the outside of the side walls of the outer packaging in the areas which are deposited by the previously aligned stapling straps of the inlay. After positioning a continuous adhesion is carried out with the help of each stapling tool. In the continuous stapling stapling is done by means of a staple anvil, which is positioned in the interior of the outer packaging relative to the staple stamp of stapling tools.

In a preferred, even more automated, form of the method according to the invention, the lid of the outer packaging, which regularly comprises a plurality of lid flaps, is automatically closed after the insertion of the flat inlay.

Processes involving blind stitching and overpacking are not covered by the invention. An outer packaging (1) made of cardboard has a rectangular bottom (2), a lid (3) arranged parallel to and spaced from the bottom (2), a total of 4 cover flaps, and the base (2) and the lid (3) interconnecting Side walls (4) on.

Above the on the floor (2) resting on packaged goods (5), which only partially fills the outer package (1) shown, parallel to the bottom (2) of the outer packaging (1) is a flat inlay (6) above the packaged goods (5) used , The planar inlay (5) has approximately the size of the surface of the Soil (2). On the edge of the flat inlay (6), fastening tabs (8) are articulated by means of film hinges (7), which are alignable by bending parallel to the side walls (4). The inlay (6) is connected to the side walls (4) in that each stitching tab (8) from the outer width of the outer packaging (1) with a plurality of staples (9) by means of a blind stitching (10) is connected.

The filling of the outer packaging (1), the insertion of the flat inlay (6) parallel to the bottom (2) of the outer packaging (1), the alignment of the fastening tabs (8), measuring the distance (11) of the inlay (6) from the upper, through the lid closable opening, the positioning of the four stapling tools in the embodiment (12) and the activation of the stapling tools (12) for fixing the stapling tabs (8) on the side walls (4) is carried out with the schematically in the FIGS. 1 and 2 illustrated arrangement (13). The assembly (13) comprises a measuring device (14) for measuring the distance of the inlay (6) from the upper opening. Furthermore, the arrangement (13) comprises positioning means for positioning the stapling tools (12) as a function of the previously measured distance (11) of the inlay (6) from the upper opening. Further, the assembly (13) comprises a controller, not shown, which causes each stapling tool (12), after its positioning, to perform the blind stitching (10) for fastening the stapling tabs (8) to the side walls (4).

FIG. 5 shows a device (17) for performing, the method according to the invention, wherein the stapling tool performs a continuous stapling.

In a frame (18) of the device (17) a conveyor (19) is arranged, which extends from an inlet side (20) to an outlet side (21) of the device (17). In the illustrated embodiment, the conveyor (19) is designed as a roller conveyor or roller conveyor. On the frame (13) In addition, a multi-axis positioning system (22) for two stapling tools (23) is fastened to the device (17) on the upper ridge bars of the setting frame (18). The three-axis positioning system (22) allows movement of the two stapling tools (23) in the X, Y and Z directions. The Z-direction corresponds to the conveying direction of the conveyor (19), the Y-direction runs perpendicular to the conveyance plane (19) spanned by the conveyor (19). The X-direction verläufz in the conveying plane transverse to the Y-direction. The Y-direction defines the height, the X-direction the width and the Z-direction the length of the on the conveyor (19) located outer packaging (1).

Along the conveying path of the conveyor (19) from the inlet side (20) to the outlet side (21) are two stop means (24a, b) which can be brought into and out of action by means of unillustrated actuators. The closer to the inlet side (20) arranged towards stop means (24a) stops the incoming outer packaging (1) in a reading position (25). The following in the conveying direction stop means (24b) stops the outer package (1) in a stapling position (26).

In the reading position (25) is the outer package (1) in the detection range of a reading device (27), for example in the form of a camera that reads a printed or attached to the outer packaging or the inserted planar inlay (6) code. This code contains at least information about the length and width of the outer packaging.

In the stapling position (26) is the outer packaging in the range of movement of the positioning system (22) for the stapling tools (23).

The structure of the positioning system (22) is described below with reference to FIG. 8 explained in more detail. The positioning system (22) consists of a movable in the Z direction portal (28). At the portal (28) two movable in the X direction tool holders (29) are arranged. On each of the two tool holders (29) one of the two stapling tools (23) is arranged movable in the Y direction.

The structure of the two stapling tools (23) is described below with reference to FIG. 11 explained in more detail. Each stapling tool (23) comprises a stapling punch (31) arranged on a carriage (30) which can travel in the Y direction and points in the direction of one of the side walls (4) of the outer packaging (1). An L-shaped support element (33) displaceable in the X direction relative to the carriage (30) is displaceably arranged on an upper, horizontal portion of the carriage (30) which extends in the X direction. For the relative movement between the support element (33) and the carriage (30) provides a drive (34), which engages on the one hand on the support element (33) and on the other hand on the horizontal portion of the carriage (30). The drive (34) is designed in particular as a linear drive. At the staple punch (31) opposite section of the support element (33) this is designed as a staple anvil (32). The staple anvil (32) causes the staple to be bent outside the tab (8) to be joined to the side wall (4) of the outer wrapping (1) during the continuous stapling operation. In this case, the guides in the stitching anvil (32) can be stirred so that the legs of the staple are bent inwards or outwards.

At the downwardly facing end of the support element (33), a pressure element (35) is arranged, which can be brought to bear on the inlay within the outer packaging. The pressure element also actuates a switching element as soon as the pressure element touches the inlay (6).

On the carriage (30) holding jaws (37) are arranged in the lower region, between which the staple punch (31) is mounted. Perpendicular to the holding jaws (37) extends in Direction of the inlet side (20) of the device (17) has a driver (36) for erecting the lid (3) forming flaps (39) which are hinged to the side walls (4) of each carton (1). Furthermore, a sensor, in particular an optoelectronic sensor, is arranged on at least one carriage (30) in order to determine the height of the outer packaging (1) in the stapling position (26).

The device (17) described above for continuously carrying out the method according to the invention operates as follows:

via the inlet side (20) continuously filled and outer packaging (1) of different size on the conveyor (19) reach into the device (17). The outer packaging (1) are supplied to the device with the lid (3) open. For this purpose, in the illustrated embodiment, the four hinged at the upper edges of the side walls (4), the lid (3) forming flaps (39) bent down so that the lid abut the outer surfaces of the side walls (4). The supplied outer packaging (1) are already filled and the flat inlay (6) is inserted into the outer packaging. In this case, the inlay (6) can be arranged parallel to the bottom of the outer packaging (1) or even at an acute angle to the bottom of the outer packaging (1) both in the X and Z directions above the packaged goods. The fastening tabs (8) are all aligned in the direction of the opening of the outer packaging. On the inlay (6) the code with information about the length and width of the outer packaging (1) is printed. This code is read in the reading position (25) by the reading device (27) designed as a camera and transmitted to the control (not shown) of the device (17).

After reading the code, the stop (24a) is momentarily deactivated by retracting the stop below the level of the conveying plane. The packing containers (1) are conveyed by the conveyor (19) further in the direction of the outlet side (21) until they are stopped by the activated stop (24b) in the stapling position (26). The further transport of the outer packaging (1) from the reading position (25) is controlled such that the stop means (24a) is deactivated only when the outer packaging (1) located further forward in the conveying direction leaves the stapling position (26) and the stop means (24b ) has been reactivated.

The FIG. 6 shows an in the stapling position (26) on the stop means (24b) with the front side wall (4) adjacent outer packaging (1). In order to center the outer packaging (1) in relation to a center line running in the Z direction of the conveyor (19), centering means (40) are arranged above the conveying plane in the stapling position (26) (cf. FIG. 7 ). The centering means (40) comprise two Z-directionally extending, in the direction of the inlet side (20) widening guide rails (41 a, b), the mizehilfe a drive synchronously with respect to the extending in the 2-direction center line of the conveyor (19) a starting position in an end position and vice versa are movable. In the end position, the guide strips (41a, b) are flush with the outwardly facing side walls (4) of the outer packaging (1). In this centered position of the outer packaging (1), the flaps temporarily fixed to the side walls (4) (FIG. 39) of the lid (3) dissolved.

The two stapling tools (23) are at this time completely in the conveying direction before the outer packaging (1). This position of the stapling tools (23) is in particular also off FIG. 8 recognizable.

The two stapling tools (23) are at this time in a lowered position in the Y direction. The controller is due to the reading of the code, the length and width of the in the stapling position (26) located outer package (1) known. Considering the known width, the tool holder (29) is moved in the X direction to align the projecting in the direction of the inlet side, sword-shaped carrier (36) parallel to the side walls (4) in the 2-direction. By way of the subsequent upward movement of the tool holders (29) in the Y direction, the drivers (36) reach between the side walls oriented parallel to the Z direction and the flaps (39) resting against them, whereby the flaps are set up in the vertical direction. At the same time, the height of the outer packaging (1) is scanned by means of the sensor (38) and the determined value is transmitted to the controller. The tool holder (29) is lifted based on the detected height of the outer package so far that the vertical portion of the support element (33) with the stitching anvil (32) can dive into the inner of the outer packaging until the pressure element (35) on the inlay (6 ) is present. At this time, the integrated into the pressure element (35) switch is triggered and signals the controller, the position of the stapling tool (23). By means of the actuator (34) of each stapling tool (23) in each case one of the tabs (8) is pressed against the inside of a side wall (4). This ensures that the tab rests flush against the inner surface of the side wall (4), so that the staple securely connects both cardboard layers together.

Taking into account the length of the outer packaging (1) detected in the reading position (25), the control of the device (17) determines the number of stitches between the side walls (4) and the tabs (8) of the inlay (6). Depending on the number of stitches to be made, the portal (28) is moved in the Z direction after each stitching, in order then to activate the stapling tools (23) again. The procedure of the portal in the Z direction is in FIG. 12 recognizable.

Of course, the device described above can also be used with stapling tools for setting a blind stitching use. In this case, the stapling tool (23) differs in so far as a support element (33) with staple anvil (32) and the actuator (34) are dispensable. The tactile switch for detecting the position of the stapling tool (23) detected in the pressing element (35) must in this case be replaced by a suitable other sensor which is suitable for detecting the position of the inlay (6) in the outer packaging (1). In particular, optoelectronic distance measuring devices which are arranged above the stapling position (26) on the frame of the device (17) and detect the position of the inlay (6) by measuring the distance between the inlay (6) and a fixed reference point are possible. The blind stitching is carried out with such a device (17), in particular with relatively thin cardboard layers to be joined together, while thicker cardboard layers are preferably connected to one another with the described continuous stitching. <B> LIST OF REFERENCES </ b> No. description 1. overpack Second ground Third Lid / opening 4th side walls 5th packaged goods 6th inlay 7th film hinge 8th. tabs 9th clinch 10th blind stitching 11th distance 12th Stapling tools 13th arrangement 14th measuring devices 15th positioning 16th cavity 17th contraption 18th frame 19th promoter 20th inlet side 21st outlet 22nd positioning 23rd tacking tool 24a, b slings 25th reading position 26th Staple position 27th reader 28th portal 29th tool holder 30th carriage 31st Heft temple 32nd clinching anvil 33rd support element 34th actuator 35th presser 36th sword-shaped driver 37th holding jaws 38th sensor 39th fold 40th centering 41a, b guide rails
